First of all, 16% of the evil lines are clear to control the "spikelet head" of rice.
For many years, the phenomenon of "spikelet head" (also known as spikelet warping) under multi-variety, multi-planting level and multi-ecological conditions has occurred in large-scale production in Jiangsu and other major rice production areas, which is characterized by small spikes and small glumes. After grain filling, the inner shell is cracked, part of the rice grains are exposed, the rice is small and beige black and brown. The occurrence is particularly serious in the Lixiahe area, coastal area, along the Huaihe River, along the Huaihe River, along the hills and other areas in Jiangsu Province. It is estimated that in recent years, the affected area of Jiangsu Province alone has been about 100000 hectares per year, and the yield of rice has been reduced by more than 100m kg, resulting in cumulative damage to rice production.

Technical measures to prevent the production of empty chaff grains in Rice
The empty grain of rice refers to the empty grain that is not fertilized and the half-empty grain that can not develop after fertilization, which has a great influence on the yield of rice. Therefore, in rice production, in addition to striving for more panicles and large panicles, it is necessary to reduce empty grains, increase seed setting rate and increase 1000-grain weight in order to obtain high yield. At present, it is the filling and fruiting stage of rice. In order to prevent the production of empty grains and achieve the goal of high yield, comprehensive preventive measures must be taken. The specific measures are as follows: 1. The physiological forms of good fruiting varieties are different among rice varieties, and the seed setting rate varies greatly.

Fertilization measures for preventing chilling injury of Rice
Fertilization cases: in 2006, in Shangzhi City, Heilongjiang Province and other rice growing areas, some rice seedlings encountered low temperatures below 17 ℃ in the early stage of rice growth, resulting in varying degrees of rice chilling injury. In Ningxia and Zhangjiakou rice cropping areas in northwest China, in the late autumn rice growth period, when the temperature dropped to less than 20 ℃ during the filling season, the rice encountered chilling injury, which was very disadvantageous to grain filling. The seed setting rate decreased by 10-20%, and the heavy ones decreased by more than 50%. Expert comments: in the northern rice-growing areas, in order to prevent the cold damage caused by low temperature weather to rice production

Technical measures of Rice Intermediate Tillage Management in Eryuan County
From last autumn to June this year, the high temperature weather of continuous drought occurred in Eryuan County, which brought varying degrees of losses to small spring crops and some large spring crops could not be sown normally. The county agriculture bureau has taken various scientific and technological measures to actively deal with natural disasters such as extreme drought, and strive to achieve the "spring loss and spring replenishment" and the annual production target. In rice production, we should pay attention to various backbone measures, such as improved varieties, dry cultivation, sparse planting and shallow planting, soil testing and formula fertilization, accurate quantitative cultivation, high yield establishment and so on. Scientific and technological personnel go deep into the front line of agricultural production and grasp science and technology.
